That's interesting as in their on-line FAQ, Cree says they approve of installation in can fixtures. We've had 42 W CFLs in there for the last 8 years and never seen evidence of overheating. However, the light is cycled a lot and I suspect the failures we've seen are related to that. Cree again states that power cycling is harmless to their LED bulb. I guess I'll get to find out!

Now I see that Home Depot has units that are specifically designed to go in a 5 or 6 inch pot light can.  I haven't noticed the color temperature, but the price ($28 each) was enough to put me off.

I'd beenusing a 150 W equivalent 42 W CFL, but they don't last long. Based on what I've seen here, I went to Home Depot and snagged a Cree 75W equivalent (18 W consumption) flood light.  It is quite bright and, as far as I can tell, RF-quiet at HF. I listened on on the AM BC band and 160-10 m during the day (so 80 and 160 are quiet) and heard nothing from it it. I also hear nothing from it on 2 m or 20 cm. So far, so good!
